BIOLOGY OF THE TERMITES OF THE EASTERN UNITED STATES. 71 
TERMITOPHILOUS INSECTS. 
The presence of termitophilous insects or "guests" in colonies of 
Leucotermes Jiavipes in the United States has been recorded by 
several writers on termites. Mr. E. A. Schwarz a has published an 
extensive list of Coleoptera associated with Jiavipes. Inquilines, or 
guests, are found only in permanent colonies and, as brought out 
by Mr. Schwarz, b might be of importance in establishing the original 
habitat of a species; that is, if a termite species had peculiar inqui- 
lines (guests that do not occur among other species of termites) in one 
country and none in another, it would indicate that the termite 
species was native to the country where the inquilines occur in its 
colonies. Mr. H. G. Hubbard found the staphylinid beetles Tri- 
chopsenius and Anacyptus in a colony with supplementary royalty, 
April 20, 1882, near Crescent City, Fla. He also found peculiar 
wingless psocids which resemble young termites in a colony of the 
latter, near Haw Creek, Fla., March 26, 1895. The note in his field 
diary reads: 
Termitophilous psocid found with termites in large log of pine, swampy hummock 
of Prairie Farm. Several specimens in alcohol, together with worker of termite. 
* * * The resemblance to a young termite is perfect, especially in mature speci- 
mens. * * * The psocid is, however, much more active than the termite and very 
difficult to capture. Immature specimens were not rare. * * * The immature 
specimens inhabit the galleries of the termites, but are not so apt to be found among 
the termites as in their immediate vicinity. 
King c records three inquilinous staphylinid beetles as associated 
with Jiavipes, PJiilotermes pilosus Kraatz, Hornalota sp., and Tachy- 
porus jocosus Say. 
All stages of small scarabseids, Homovalgus squamiger Beauvois and 
Valgus canaliculatus Fabricius, are commonly found associated with 
termites in decaying wood in Maryland, Virginia, West Virginia, and 
North Carolina, and are probably truly inquilinous. From the mid- 
dle of July, 1914, prepupal larvas and pupaB of Homovalgus squamiger 
were commonly found in decaying wood infested by termites and in 
the galleries of termites in Virginia. Adults of this beetle begin to 
mature about the middle of August. The larvae construct oval pupal 
cells in the decayed wood or make them of earth; the interior is 
smooth and glossy. This beetle is probably a true inquiline.
